Guide and guard unit for steel rolling and steel rolling device

Abstract

The invention provides a guide and guard unit for steel rolling and a steel rolling device. The guide and guard unit for steel rolling comprises a guide and guard body and a roller, wherein a rotating shaft is arranged on the guide and guard body, two bearings distributed up and down are arranged on the bearing, the roller is rotationally connected onto the rotating shaft through a bearing, a water channel is arranged on the guide and guard body, the guide and guard body is provided with an upper water spray port, a middle water spray port and a lower water spray port in the direction of the rotating shaft, the water spray ports are all communicated with the water channel, and one sides of the water spray ports, on the roller, face to the roller. By arranging the water channel on the guide and guard body and arranging corresponding water spray ports in positions corresponding to the upper, middle and lower parts of the roller, even temperature reduction to the roller can be achieved through the three water spray ports, so as to ensure that the contact surface between the roller and steel material is cooled evenly by cold water, the phenomenon of roller stuck caused by part over temperature due to uneven cooling can be avoided, and the reliability of the steel rolling device is enhanced.

Description

technical field [0001] The invention relates to steel rolling machinery and equipment, in particular to a steel rolling guide and a steel rolling device. Background technique [0002] At present, with the continuous progress of industrial and urban construction, the demand for steel is also increasing. In the prior art, steel rolling devices are usually used to produce steel. The rolling device usually includes: a rough rolling mill, a pre-finishing mill, a finishing mill and a reducing and sizing mill arranged in sequence. During the steel rolling process, the roller on the guide is heated and heated in contact with the steel, so it is necessary to cool the roller. Usually, a nozzle is installed on one side of the guide, and water is sprayed on the roller on the guide through the nozzle to cool the roller. It can be seen from the above that during the working process of the guide, the external nozzles are used to spray water to cool down, and the cooling of the rollers is...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a steel rolling guide and a steel rolling device, which are used to solve the defect that the guide in the prior art is prone to overheating and jamming due to uneven cooling, resulting in low reliability of the steel rolling device, and to achieve uniform cooling of the steel rolling guide. The rollers of the guard reduce the jamming of the rolling guide and improve the reliability of the rolling device
